For example, if you see an outfit you really want but don't yet have enough in your 'Clothing' envelope, you can choose (prioritize) to transfer money from another envelope, say, 'Entertainment' (as opposed to, say, 'Rent'.) Or you can use the tool called the 'Future Balances Calculator' to answer the question "If I hold off buying now, when will I have the necessary funds in that envelope?" or perhaps the question "How much will I have in my 'Paris Vacation' envelope when that date arrives?" 'Spend Control' also generates a number of reports, such as 'Current Budget' and 'Current Balances' which you can then email to yourself or to someone else.
